About the Airtac GAFC Air Service Unit GAFC400C15ASK
This GAFC400C15ASK is a two-piece F.R.L. combination from AirTAC: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. The 1/2in port and 1810 g mass place it in the mid-size class, a step up from the GAFC300's 1020 g for lines that need more condensate and oil capacity.
The metal bowl holds 100 cc of condensate and the oil bowl 185 cc, so the service interval is generous for a machine header. It regulates from 0.15 to 0.9 MPa (20-130 psi) with a 40 um element, and the circular gauge reads in MPa/psi. The automatic drain clears water without an operator, and the reverse-flow valve is fitted as an ordering option.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFC Air Service Unit GAFC400C15ASK Is Used
CNC coolant lines
Regulates air for a CNC machine's coolant system, where the 40 um element and automatic drain keep the line clear of moisture and the 1/2in port matches the header.
Assembly station headers
Feeds a multi-station assembly line with filtered, regulated air and oil mist for pneumatic tools, with the 185 cc oil bowl reducing refill frequency.
Packaging equipment
Supplies a packaging machine's actuators and valves, where the 100 cc condensate bowl and automatic drain support continuous shifts without manual attention.
Is the Airtac GAFC Air Service Unit GAFC400C15ASK the Right Air-Prep Unit?
Choose this GAFC400C15ASK when a 1/2in port feeds a multi-station machine header. The metal bowl is specified by the C code, with the same 1.0 MPa (145 psi) max and -5 to 70 C range as PC or nylon versions, so confirm it suits your environment. The automatic drain (A) handles wet lines unattended, while the standard type (S) covers 0.15-0.9 MPa (20-130 psi) with a 40 um element and a fitted MPa/psi gauge on PT threads. The K suffix adds the reverse-flow valve, which the catalogue draws as a separate symbol. Spare parts are the GAFR400-15 filter-regulator and GAL400-15 lubricator, both orderable separately. With a 1.0 MPa max supply, you have only about 0.1 MPa above the 0.9 MPa regulated top, so plan the inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (1/2" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter-regulator first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 g unit on its bracket, not on the tubing.
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a plain GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C15ASK FAQ
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works from -5 to 70 C, uses ISO VG 32 oil, has a 100 cc drain bowl and 185 cc oil bowl, and weighs 1810 g.
The K suffix indicates a reverse-flow (reflux) valve is fitted. The catalogue shows it as a separate pneumatic symbol on its own page, and it is an ordering difference from the standard GAFC400. The unit still functions as a filter-regulator plus lubricator with the same port and pressure range.
